This year's April 8 home opener, against the Mets, will provide fans a chance to welcome a new season and celebrate one of the most memorable events in baseball history. In 1974, across the street at the old Atlanta-Fulton County Stadium, Aaron hit his historic 715th home run, breaking Babe Ruth's "unbreakable" record.

The home plate-shaped patch has a navy background and Aaron's autograph running across the number 715, which is red. The top of the patch is adorned with the words "40th Anniversary." The bottom features the feather that was on the Braves jerseys in 1974.

"We are delighted to honor Hank and recognize this momentous occasion," Braves president John Schuerholz said. "It was such an enormous milestone for him, for our team and for Major League Baseball, and we believe it deserves a season-long celebration."
